ENGINE
Valves and springs - refit 1. Lubricate valve stems, guides, spring seats, valve springs, spring cups and collets with engine oil. 2. Lubricate new valve stem oil seals with engine oil and fit to valve guides. 3. Fit spring seat, insert valve into its respective guide, fit valve spring and spring cup. 4. Compress valve spring using tool LRT-12-034 and fit collets. 5. Remove tool LRT-12-034. 6. Tap spring cup with a soft mallet to ensure that collets are correctly seated. 7. Repeat above procedures for remaining valves.
Cylinder head gasket selection
CAUTION: New cylinder head gasket should be same thickness as the original. If, however, cylinder head, pistons or crankshaft have been replaced, it will be necessary to check piston stand proud in order to determine the correct thickness of gasket.
1. Position a magnetic base DTI to cylinder block top face adjacent to number 1 cylinder bore. 2. Position stylus of gauge to cylinder block top face on edge of number 1 cylinder bore; zero gauge. 3. Rotate crankshaft in a clockwise direction until numbers 1 and 4 pistons are at TDC. 4. Position stylus of DTI gauge near edge of piston crown, measure and record number 1 piston stand proud. Measurement must be taken at front and rear of piston and highest protrusion figure recorded. 5. Repeat above procedures for remaining pistons.
